Abstract

PURPOSE: To improve display effect by providing a part for control, wherein intervals of time of pulse light emission is made short enough to obtain continuity of the after-image effect of the eye, in sequential control. CONSTITUTION: When a pulse driving circuit 3 controls the light emission of a visible light emission part(LED) 1, pulse light emission is performed at a set frequency and LEDs 1 in a stationary state is seen similarly to the light emission of the LEDs in a normal state. When a rotary blade 2 is rotated, about tens of LEDs 1 are clearly viewed because of characteristics of the pulse light and the after-image phenomenon of the eye. When the rotation is sufficiently fast, the LEDs 1 are viewed as if tens of LEDs 1 emitted light while surrounding the periphery of the rotation, and the viewed individual LEDs 1 turn on and off repeatedly and momentarily, so an impressive display is made. Consequently, various display effects can be obtained.
